Hexadecimal Array

Question:
I am trying to create an array of 256 hexidecimal values but am having some problems. How do I create a valid array using hexadecimals?

Answer:
Whether you use hexadecimal values, straight integers, octal values, or unicode doesn't matter when creating an array of primitive numbers (including characters). What matters is that you define the values that you require and that they are compatible with the primitive type you are defining. To create an integer array of the values 0 to 16, you could do either one of the following:

int[] array1 = {
   0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
};

int[] array2 = {
   0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a,
   0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x10
};
